The invention provides an air conditioning system fault diagnosis and predictive health management method and equipment. The method comprises the steps of system operation state performance feature extraction, fault diagnosis and fault category recognition and predictive health management decision support. The method is suitable for constant-air-volume, variable-air-volume and full-fresh-air air conditioning systems, and the fault detection accuracy and predictive health management capacity can be improved. Through comprehensive application of various technical means, automatic and intelligent processing of air conditioner system fault diagnosis and predictive health management is achieved, the stability and reliability of the system are improved, and the maintenance cost and the loss of equipment faults are reduced. Timely and accurate fault diagnosis and predictive health management information are provided for maintenance personnel, and intelligent management and maintenance are realized. 本发明提供了一种空调系统故障诊断和
